Motorized fire dampers electical wiring
To connect the dampers to the power supply, proceed as follows:
• Check that the voltage and electrical frequency are equivalent to
those of the motor of the servomotor (check the motor's informa-
tion label);
• Make the connections as shown in the below diagram.
